corner cabinet is not wasted space
i like the round or arch shaped island
think about opening that small window to bring more light into the kitchen also may a skylight in that area. Also a bay herb window would work well in that space
built in ovens are wonderful!
like this look
like this cabinet idea ... less overhead cabinets would make kitchen appear larger and the undercounter cabinets should consists of drawers instead of wasted space .... i.e. drawers for dishes and pots and pans etc....
taking down that wall may look a little like this .....
this is what drawers look like !!!
like this island with the prep sink
like these under counter sinks ... make sure your isnks are deep
